摘　　要：随着5G高精度信息化普及,通信波段信息传导精确性成为广泛研究讨论的热点问题。电力行业为搭建高精度信息网络,开始逐渐重视通信信息网络,并逐步展开专项研究。从稳定通信基线恢复出发,通过搭载COSTAS环建模来提高载波通信恢复稳定性,提高供电网络的高精准度信息传送,并解决信息在电力通信通道传输过程中易受到空间介质干扰问题。同时,对传统COSTAS环进行改进,大大简化了COSTAS环结构,在保持稳定性的同时,提升了算法计算效率及可靠性。最后,为验证改进COSTAS环稳定性,通过Simulate建模对算法进行验证,结果证明该方法在载波恢复方面具有较强的抗误码效能,能很好提升低压电力载波的抗滋扰能力。With the popularization of 5G high-precision informatization,the accuracy of communication band information transmission has become a problem of extensive research and discussion.In order to build a high-precision information network,the power industry pays more attention to communication information network,and gradually carries out special research.It starts with stable communication baseline recovery,it uses COSTAS to improve the stability of carrier and avoid the influence of the space medium.It simplifies the structure of COSTAS to improve the speed of this algorithm.Finally,to verify and improve COSTAS loop stability,the algorithm is validated through simulate modeling.The results show that this method has strong anti-error performance in carrier recovery and can improve the anti-nuisance ability of low voltage power carrier recovery.
